My guess would be the murders and DA office investigation got a higher priority than insurance fraud for the GJ's time. And I'm pretty sure that's what it was, since the Insurance folks were on the agency list, and mental health wasn't. So when they finally got to NN AH, they uncovered enough to figure out something was going on. But didn't have time to take it to the point of issuing indictments. Thus the paragraph saying this needs more investigation.

Hopefully this gets picked up when the next GJ is empaneled. Or law enforcement finally gets a clue, between this and the suppressed IG report, and drops on AH like a rock.

I agree. I would imagine another grand jury will be impaneled to address the alleged ( ) fraud and criminal ( ) accusations.
